Professional Applications & Engineering Value

This heavy-duty aluminum threaded pipe nipple solves critical industrial challenges where corrosion resistance, pressure integrity, and environmental compliance intersect. The seamless 6061 aluminum construction prevents failure points that commonly occur in welded alternatives, making it ideal for compressed air systems, hydraulic oil lines, and water processing applications where contamination or leakage cannot be tolerated. The NPT threaded connections on both ends ensure compatibility with standard industrial piping systems while maintaining Class 150 fitting and Class 125 flange pressure ratings. Engineers specify this ASTM B241 compliant solution for its reliable performance in chemical plants, manufacturing facilities, and utility systems where aluminum's lightweight properties reduce structural load while maintaining operational safety.

Specification Summary & Compliance

This 2 1/2" Schedule 40 pipe nipple features precision NPT threads on both ends with dimensional accuracy meeting industry standards (2.469" ID, 2 7/8" OD, 0.203" wall thickness). Manufactured to ASTM B241 specifications for aluminum pipe, the product maintains consistent mechanical properties and dimensional tolerances. Compliance with RoHS 3 (2015/863/EU) ensures environmental responsibility, while the construction meets pressure class requirements for industrial piping systems with aluminum fittings and flanges.
